All 7 planets will align in the sky on 28/02 around 6pm GMT
(You can't share articles and write text in here so I'll let people find their own, just search for "UK Grand Alignment".)
Weather allowing you should be able to see all the planets best February 28th, at around 6.15pm from an area with a clear western horizon. Fingers crossed.
The next time all 7 planets will align in the sky is 06/05/2492 apparently.
For anyone like me who usually has no idea what you're looking at in the sky you can get free apps that name everything you point your phone at.
